(Cl. 6810) ABSTRACTOF THE DISCLOSURE Yarn on bobbins is dyed when seated on perforatedbobbin-carrying pipes, which in turn are connected to a mobile pipesystem attachable to a source of treatment liquor. The flow path ofliquor is uniform through all yarn-filled bobbins. The yarn-filledbobbins are spin-dried by structure releasing the bobbin-carrying pipesonto individual rotating spindles.

The present invention is directed to a textile-dyeing device orinstallation. This installation has a circulating pipe system for thecirculating liquid dye consisting of a stationary pipe system and of amovable pipe system on a loading or feeding carriage which is suitablefor passing or traveling through a dyeing station and at the same timealso for traveling through consecutive treating stations in an endlesspath or course. The loading or feeding carriage is provided withperforated pipes for receiving the material. The perforated pipescarrying the bobbins or spools of yarn must be constituted as verticalbobbin-carrying pipes upon which the bobbins which are intended to bedyed are concentrically slipped or inserted. The present invention thusdyes bobbins or spools of yarn. Addition ally, the present invention isdirected to and concerned with the loading or feeding carriage. Thiscarriage comprises a pipe system which consists of pipes being arrangedin the vertical central plane of the carriage. Laterally projectingdistributor pipes extend from this piping and the bobbin-carrying pipesare, in each case, adapted to being mounted thereon in a suspendedmanner and may be coupled or connected thereto. The loading or feedingcarriage has a holding device actuated jointly for the attachment andfor detachment of the bobbin-carrying pipes. This arrangement renders itpossible for all of the bobbin-carrying pipes at the loading or feedingcarriage to be coupled and, uncoupled.

Furthermore, the present invention proposes two types of assemblybetween the distributor pipes and the bobbincarrying pipes. One of theseassemblies is intended for the passage of the dye liquor through thebobbins from the inside toward the outside, and the other for thepassage of the dye liquor from the outside to the inside.

An object of this invention is to provide a new apparatus for dyeingyarn.

The installation will now be described in further detail with referenceto the drawings, wherein:

The installation as illustrated consists basically of Thebobbin-carrying pipes 2 with the yarn-bobbins 3 are suspended on theloading carriage 1. The loading carriage is provided with wheels 4 whichrun in the U- shaped rails 5. By means of the transverse conveyor dolly6, the loading carriage 1 is placed ahead of the pressure tank 7 sothat, after locking door 9 is rolled open, it may be introduced into thetank 7 of station A by means of a pneumatic pushing device 8. Thetransverse conveyor dolly 6 runs or travels on the rails 10 and is movedby means of a drive motor and transmission 11 (FIGURE 2). The transverseconveyor dolly carries on its top the U-shaped rails 5 and the loadingcarriage 1.

The pipe system of the loading carriage consists of the vertical risers1a and the horizontal distributor pipes 14 which jointly constitute apiping which is arranged in the vertical central plane of the carriage.The distributor pipes 14a and, respectively, 1412 extend laterally inboth directions from the uper horizontal distributor pipe 14. Attachedand coupled to distributor pipes 14a and 14b are the bobbin-carryingpipes 2. Pipes 2 are retained in each case, by lug portions 58a ofhook-shaped levers 58.

Each carriage 1 (FIGS. 1 and 2) has two pipe couplings 15 which may becoupled with the pressure line 16 of the circulating pump 17. The pumpis connected, with the suction pipe 18 which connects at its other endto the lowest point of the trough-shaped lower portion 19 of thepressure dyeing tank 7. q

The liquid dye is prepared in concentrated form in a storage containeror tank 20. A certain quantity is removed from this tank, measured inthe measuring tank 21 and mixed with a specific quantity of water fromthe water system 22. The inlet or lead supply into the pressure tank '7takes place through the valve 23. When the two roller-type doors 9 inconjunction with the packings 24 have hermetically sealed the tank 7,circulating pump 17 is put into operation. The liquid dye circulatesthrough the suction pipe 18, through the pump 17 and the pressure lines16 and, from there, will pass into the pipe system of the loadingcarriage by way of the pipes 1a, 14, the distributor pipes 14a and 14binto the bobbin-carrying pipes 2 and from there into the yarn-bobbins 3and impregnate the yarn wound on the bobbins as shown in FIGURE 3. It ispossible also to pass the dye liquor through the bobbins from theoutside toward the inside, as shown in FIGURE 4. In this case, theliquid dye is discharged through end-face openings 70 of thebobbincarrying pipe. As has been mentioned before, the liquid dye iscollected in the trough-shaped lower portion 19 of the pressure dyeingtank and pumped again into circulation.

Heating of the liquid dye to a desired temperature may take place eitherby adding live steam which may be introduced through the connectingpiece 25 (FIGURE 1), or by means of a heat exchanger 26 (FIGURE 2), orby both means.

After the completion of the dyeing process which resuires approximatelyfrom 8 to 20 minutes, the used bath is discharged by way of valve 27(FIGURE 2) and the tank is thus rendered pressureless.

FIGURES 3 and 4 show the two diiferent ways of guiding the liquid dyethrough the material to be dyed.

FIGURE 3 shows an apparatus for passing the liquid dye from the insideto the outside of a bobbin. In each case, the same bobbin-carrying pipesmay be used. Different distributor pipes 14a or 1417 are required ineach case. These pipes are mountable upon individual loading carriagesas desired.

The bobbin-carrying pipe 2 has a flanged-coupling at its bottom. At thetop of the pipe, at flanged element 2b is arranged for axialdisplacement. The flanged-coupling elements will compress theyarn-bobbins axially. The upper flanged element may be locked, for thispurpose, with the perforated pipe 2 by means of an elastic spring bolt20.

As shown in FIGURE 4, a jacket 30 is disposed at the distributor pipe14b which consists of a perforated inner liner 31 and a closed outercover 32. The jacket 30 is open at the bottom thereof so that thebobbin-carrying pipes 2 with the bobbins 3 may be introduced. At the topof the jacket there is an opening with a sealing element 33. The end ofthe bobbin-carrying pipe is inserted through this opening and sealed.The liquid dye circulates-as shown by the arrowsthrough the pipes of thecarriage into the interspace between the liner and cover 31 and 32, fromthere through the perforated jacket 31, and from the outside through theyarn-bobbins 3 into the inside of the perforated carrier pipe 2. It mayflow out at the top and at the bottom through the openings 70 and becollected in the lower portion 19 of the pressure dyeing tank.

When the dyeing has been completed, the doors 9 will be opened and theloading carriage is transported from station A to station B. After thedoors 9 have been opened a new loading carriage 1 will be introducedinto station A. The transfer of the carriage is again effected by apneumatic inserting device 8. The roller-type door 9, in closing pushesinclined surface 28 of the door (FIGURE 1) against roll 29 of thecarriage and pushes the carriage further ahead the distance which isrequired for the door to close.

The treatment of the yarn-bobbins in station B consists of rinsing andfurther treatment, if desired. Station B has an open vat 40 (FIGURE 2)to which is connected, at the lowest point, the suction line 41 of thescavenger pump 42. The pressure line 43 may again be coupled with thepipe system of the carriage 1 by way of connecting pieces 15 and 1-6 andpipe couplings. Different rinsing or finishing baths are supplied to thevat 40 through the conduit 44 and controlled by valve 45.

The drain or discharge of the used baths at station B is made throughthe discharge valve 46. Any heating of the baths which is necessary maybe made by heat exchanger 47.

After completion of a cycle at a station, one carriage each will travelto the next station, for example, the carriage from station B willtravel to station C.

As shown in FIGURE 6, station C consists of centrifugal spindles 50below the level of rails 5. The rails for receiving the carriage 1 aresecured, in this station, to the piston rod 52 of cylinder 53 by meansof cross member 51. By actuating this cylinder with compressed air orpressure fluid, the carriage 1 may be raised and lowered. The loweredposition of the cross member is shown in FIGURE 6 by reference numeral51a.

When the carriage is lowered, the perforated carrier pipes 2 with theyarn-bobbins 3 are lowered onto an extension 54 of the spindles St). Theperforated bobbincarrying pipe is centered by opening 70 of the flangedelement 2a and in a centering ring 55. In FIGURE 6, the left-hand upperpart of the figure illustrates a bobbincarrying pipe 2 with yarn-bobbins3 being slipped on or inserted, the passage of the liquid dye takingplace from the outside to the inside. The right-hand upper part of thefigure illustrates a carrier pipe 2 with yarn-bobbins 3 for a passage ofthe dye liquor from the inside toward the outside. In this arrangement,the centering piece 56 for the centrifugal spindle 54 is slidablyarranged in the perforated pipe 2 so that it will rest on the flangedelement 211 when it is removed from the centrifugal spindle. Thus theliquid dye will not be discharged at that point and will pass throughthe yarn-bobbins. When putting the centrifugal spindle into operation bymeans of the motor 57, the perforated pipe 2 with the yarn-bobbins 3 iscaused to rotate and the adhering water is centrifuged After drying thecarriage 1 is lowered again by means of the cylinder 53. At that time,the yarn carriers being again in the position of rest will slide intothe connections of the carriage 1 being equipped with sealing rings 33.

The levers 58 are rotatably attached to the carriage 1 with a bearingpiece 59. The upper lever part is drawn toward the center of thecarriage 1 by the spring 60 so that lug portion 58a will automaticallygrasp or clamp under the flanged element 2a. The upper parts of thelevers 58 rest against flat sections 61 (FIGURES 5 and 6). These flatsections are suspended by several clips or shackles 62 which arepivotally attached to the carriage. The sections 61 are displaced bymeans of a piston 63, piston rod 64 and traverse member 65 so that thesections 61 spread outwardly by means of shackles 62. By this action thelevers 58 will cause lug portions 58a to move away from under the plate2a and will release the carrier pipes. The piston drive 63 is rigidlydisposed at each station where the disengagement of the carrier pipes isnecessary (see in this connection FIGURE 5).

The locking of the carrier pipes takes place automatically by means ofthe hook-shaped levers 58 in that the lung portion 58a snaps under theflanged-coupling element 2a of the carrier pipe (see in this connectionFIG- URE 4). The motion of piston 63 is now reversed and spring 60 willurge lugs 58a to clasp flanged element 2a.

After the carriage has traveled from station C onto the transverseconveyer dolly 6a, it is transferred ahead to station D by the movementor displacement of the transverse conveyer dolly and inserted into thedryer at D by the pneumatic piston 8a. After drying the carriage istransported to station E and unloaded there. The unloading may takeplace in precisely the same manner as has been described for thedrainage operation in FIG- URE 6. By lowering the carriage 1 by means ofpiston 52, the carriage is lowered and released by actuation of thehook-shaped levers 58.

When the carriage 1 is raised it will travel into station F in order toreceive there new carrier pipes with undyed yarn-bobbins. The receivingoperation is effected in a manner analogous to the procedure which hasbeen described for the drainage, i.e., by a renewed lowering of thecarriage and coupling the carrier pipes.

For the so-called reductive treatment which is frequently applied indyeing, a station B1 may additionally be disposed behind station B whichoperates in principle like station E.

Station C may also be equipped as a suction station. In that case, asuction device is present which sucks off the adhering water rather thancentrifuges it as shown in FIGURE 6.

It should be understood, of course, that the foregoing disclosurerelates to only preferred embodiments of the invention and that it isintended to cover all changes and modifications of the examples of theinvention herein chosen for the purposes of the disclosure, which do notconstitute departures from the spirit and scope of the invention setforth in the appended claims.
